Climate Change Is Killing Butterflies in the American West

Butterflies play essential role in pollinating wild plants and crops. Which makes a new study published in Science on Thursday such bad news. It shows the climate crisis is posing an existential threat to their survival, particularly in the American West.Read more...

Underwater Robot Stealthily Swims With a Propulsion System You Can't See

Sound travels faster and farther underwater because it’s denser than air, and that can make it harder for researchers trying to study marine life who get an early heads up to go into hiding. But a new underwater robot could move stealthily through the waves using a propulsion system that doesn’t rely on a propeller or…Read more...

Humans Have Completely Transformed How Water Is Stored on Earth

Human fingerprints are all over the world’s freshwater. A new study published Wednesday in the journal Nature shows that while human-controlled freshwater sources make up a minimal portion of the world’s ponds, lakes, and rivers, they are responsible more than half of all changes to the Earth’s water system.Read more...

Extreme Rainfall Has Been Linked With Low Birth Weight in Babies

Increasing extreme weather events is wreaking havoc across the globe, and may be harming the health of newborn babies in some of the world’s most remote and vulnerable populations. New research published Monday in Nature Sustainability finds a strong link between extreme rainfall events in the Amazon, which have been …Read more...

Unseasonable European Warmth Smashes All-Time February Temperature Records

Winter has receded in Europe this week. Temperature records are falling as unseasonably warm weather sweeps across the continent delivering an early spring thaw, even while neighboring Russia is simultaneously going through a deep freeze.Read more...

A Huge Red Flag Just Popped Up in a Little-Studied Region of Antarctica

Glaciers in Antarctica are turning the concept of “glacial pace” on its head. A new study of a little-observed area on the continent finds that rising heat is making ice streams flow faster, which has worrisome consequences for sea level rise.Read more...

A Major Ocean Current May Be Hurtling Towards Collapse

The ocean may have less time than we thought before massive, irreversible shifts take place. A new study finds that a crucial ocean system may reach its “tipping point” sooner than predicted if the rate of climate change continues at a breakneck pace.Read more...

Russian Gas Tanker Shows Arctic Is Navigable Year-Round Now

Every day, the Arctic slips further into an unstable state. The latest sign: A Russian icebreaker and liquid natural gas ship have traversed the Northern Sea Route in February for the first time due to exceptionally low and weak sea ice cover.Read more...

Scientists Found Unexpected Life Half a Mile Under an Antarctic Ice Shelf

Back in 2016, a team of marine scientists from around the world traveled to Antarctica to learn about the mysterious ecosystems under its vast ice shelves. One team of geologists was tasked with videos from beneath the Filchner-Ronne Ice Shelf, which is on the South Eastern Weddell Sea.Read more...

The Siberian Tundra Is Doing That Exploding Thing Again

The Siberian tundra is still out here exploding. A new study from the Woodwell Climate Research Center has identified three new craters in the region’s increasingly volatile permafrost, and the climate crisis is to blame.Read more...

Glacier Breaks, Unleashing a Monster Flash Flood in Himalayas

At least 20 people are dead and up to 125 still missing after a piece of a glacier in the Himalayas collapsed on Sunday, causing flash floods and destroying a dam in its path. Video footage shows a colossal rush of water and rocks roaring through a mountain valley in the northern Indian state of Uttarakhand after a…Read more...

The Arctic Ocean Was Once Filled With Fresh Water, New Research Suggests

Stunning new evidence suggests the Arctic Ocean was covered by a thick layer of ice and filled with fresh water on at least two occasions during the past 150,000 years. The observation could finally explain strange and dramatic climate anomalies associated with these glacial periods.Read more...

17th-Century England Had Some Seriously Horrible Weather

Recent years have brought record-breaking wildfires, hurricanes, and other natural disasters supercharged by climate change. But even to our jaded modern eyes, the weather that befell Bristol in Western England at the turn of 17th century is pretty shocking.Read more...

This Giant Ice Cube Represents How Much Ice We're Losing Every Year

We talk about ice a lot here on Earther—or more specifically, the growing absence of it. A new study puts what’s happening to the planet in striking perspective. While I can tell you the results show 1.2 trillion tons of ice disappeared every year since 1994, it’s a lot easier to grasp as a visual.Read more...
